DEMOUNTABLE WHEEL.

Specification of Letters Patent.

Patented N ov. 22,1921.

Application led December 29, 1919. Serial No. 347,980.

To all whom t may con cern.'

Be it known that I, HENRY E. HoLLEY, a citizen of the United States, and a resident of Otisville, county of Orange, and State of New York, have invented a new and Improved Demountable Wheel, of which the following is a full, clear, and exact description. y

This invention relates to demountable wheels, and has reference more particularly to a demountable wheel provided with an irregularly shaped hub which is fitted to a rim-bearing member.

An object of this invention is to provide a demountable wheel which will be cheap to construct, and which may be easily and quickly removed from the hub.

Reference is to be had to the accompanyin drawing forming a part ot this specification in which it is understood that the drawing is merely illustrative of one example ot the invention together with certain modifications, and in which- Figure 1 is a central, sectional view on the line 1 1 of Fig. 2 through one form ot my demountable wheel specially adapted to the rear axle of a vehicle.

Fig. 2 is a section through Fig. 1 on the line 2 2.

Fig. 3 is a perspective view ot the hub of my improved demountable wheel.

Fig. 4 is a sectional view through Fig. 5 on the line 4 4 showing a modified form of my demountable rim adapted to a front axle.

Fig. 5 is a' section through Fig. 4 on the line 5 5.

Fig. 6 is a perspective view of the hub of the wheel shown in Fig. 5.

Referring to the accompanying drawing by numerals, 10 indicates a rear axle of any vehicle such as an automobile on which is secured by means ot a key 11, a washer 12, and a nut- 13, a hub 14. The hub 14 has threee distinct sections, the first of which is an annular flange 16; the second is a trusto-pyramidal section 17 having a hexagonal or other polygonal base; and the thirc section 18 is substantially cylindrical but is provided with two chordal plane surfaces 19 extending parallel to the axis oi said hub. This form oit demountable'wheel is specially adapted for use with a wheel having a disk 20 to support the rim rather than the spokes, and said disk is preferably secured between two supporting members 21 and 22 by means ot' a plurality of bolts 23. The members 21 and 22 and the disk 20 when fixed together by the bolts 23 have an internal shape similar to the section 17 of the hub 14 so that the two register. The bolts 23 are loosely fitted in the supporting member 21 and the disk 20, but has a threaded portion 24 which engages similar threads on the supporting member 22. The bolts 23 also have dowellike ends 25 which register with holes 26 in the fiange 16, said ends forming auxiliary locking means to prevent the rotation of the disk 20 around the hub 14. A lug 27 is also formed on each face ot the section 17, said lugs engaging similarly shaped grooves in the supporting member 22 so that said lugs will also assist in preventing rotation of the disk 20 about the hub 14.

A washer 28 is rotatably mounted on the section 18 and has an outside shape substantially that of the outer end of the section 17 and the support 21 so that when the points ot said washer are turned so as to enga e the fiats of the support 2l, the disk 20 will be locked onto the hub 14, but when said washer 28 is turned so that its shape registers exactly with the shape of the member 21, the disk 20 may be removed by sliding it outwardly over thel washer 28. In order to hold the washer 28 securely against the outer surface oi the member 21, the outer end of the section 18 is threaded to receive a cap 29, said cap having a portion 302L larger in diameter than the section 18, said portion engaging the washer 28 securely when the wheel is locked to the hub 14. The outer end of the cap 29 may be provided with fiats not shown so that a wrench may be applied to screw or unscrew said cap on the section 18. lVhen it is desired to remove the wheel from the hub 14, said cap is loosened slightly so that the washer 28 may be rotated about the section l18 until it registers. with the opening in the supporting member 21, and when the wheel may be slipped out over said washer 28 and the cap 29. In order to secure the washer 28 in either a locked or unlocked position, a fiat springy wooden spokes 32. The hub 34 is also formed in three sections. the first beingan annular flange 42, the second being a section having an outer surface 43 which .is cy lmdrcal adjacent the flange 42 and ellipt1cal on the end opposite said flange, and a third section 43a which is cylindrical. A collar 44 has an inner shape similar to the surface 43 and an outer cylindrical surface on which is mounted a ring 45 through which passes 4bolts 46 which are screwed to an annular flange 47 on the collar 44, thus securing the spokes 32 between said flange 47 and the 4ring 45. These bolts 46 are constructed similar to the bolts 23 and have dowel-like ends 48 which engage holes in theflange 42 thus providingl auxiliary locking means to prevent thevwheel from rotating about the hub 34. A washer 449 is rotatably mounted on the section 43e and has an outer elliptical shape similar to the outer end of the surface 43.. Thus when the washer 49 is in the position shown in Fig. 5, the collar 44 is locked on to the hub 34, Vbut when this secure the collar44 on the hub 34, the outer end of the section 43*y is threaded to receive a cap 51, the inner end of said cap bearing against the washer 49, and the outer end of said cap being provided preferably ywith flats not shown to engage a wrench. A washer 52 is interposed between the collar and a nut 53, so that the hub 34 is held securely on the axle 33 and said cap 51 is ofI 45 such size as to contain said nut 53.

A It isunderstood that any of the forms may be used on either the front or rear axle by suitably modifying the hub but in each form, the rim bearingv member is interchangeable between any of the wheels as it fits the hub whether said hub is modified to lit arear or a front axle.

, I would state in conclusionthat while the illustrated example constitutes a vpractical embodiment of the invention, I do not limit myself strictly` to 'the mechanical details herein illustrated since manifestly the same can be considerably varied without Adeparturefrom the spirit of'the invention .as defined in 'the lappended claims. v

,"Having thus described my invention, I
